Percent increase : (new number - original number) / (original number)....x 100
(40 - 25) / 25 = 15/25 reduces to 3/5.....x 100 = 60% profit
Answer:
f(- 2) = 9
Step-by-step explanation:
To evaluate f( - 2) substitute x = - 2 into f(x), that is
f(- 2) = (- 3 × - 2) + 3 = 6 + 3 = 9
500 before training session
250 at start of session
(1 hr = 60 min.....60/15 = 4...so there is 4 fifteen minute intervals in 1 hr.)
150 every 15 minutes...150 x 4 = 600
so total amount of water is : 500 + 250 + 600 = 1350 ml
Answer:
4 × (3 + 7) = (4 ×7) + (4 × 3)
Step-by-step explanation:
If you go by the order of PEMDAS you would do the parentheses first. 3 + 7 =10. 10 × 4 = 40. Then you would just use the distributive property and do (4× 7) + (4 × 3)
4 × 7 = 28 and 4 × 3 = 12 28 +12 =40
